Multi-Level Authentication

Definition ∞ Multi-level authentication, often called multi-factor authentication (MFA), requires users to provide two or more verification factors to gain access to an account or system. These factors typically fall into categories like something the user knows, something the user has, or something the user is. It significantly enhances security by adding layers of protection beyond a single password. This method greatly reduces the risk of unauthorized access.
Context ∞ News concerning multi-level authentication in the crypto sector highlights its critical role in safeguarding digital assets against theft and unauthorized access. Exchanges and wallet providers strongly recommend or mandate MFA to protect user accounts. The continuous evolution of cyber threats necessitates increasingly robust authentication methods to secure valuable digital holdings.
